If this had been the case, you would indeed have been right: such a '2GB' card would last longer because of spreading the write cycles around.
Look up "wear leveling" for flash memory. This is done at a very low level. The memory device has no knowledge of its partitioning and after a few writes, the mapping of logical sector number to actual device location becomes spaghetti. That is why "defragmenting" a flash memory device is a bad idea.
